![]() ![]() When the mushroom mycelium has consumed most of the substrate, it will stop expanding to search for nutrients. This process is also called pinhead initiation, formation, knotting, pin setting, or fructification. Mushroom pinning is the first process that signals that the mycelium is ready to fruit. This increases the chance of contamination as well, since uncolonized spaces in your substrate may sprout mold formations. This longer waiting time increases the chance of contamination and burdens you with more effort of misting.Īnother case, if you induce pinning early, is that the mycelium will start pinning without fully colonizing the substrate. If you induce pinning too early, you may have to wait longer for pinning as providing the ideal conditions may cause the mycelium to continue depleting the substrate. If you induce pinning thinking that the substrate is ready without waiting for these visual cues, chances are that you might mess up the growing cycle of your mushrooms. Take note only to provide these conditions once you see visible cues. High humidity level of around 85% or more.Low temperatures around 53 to 64☏ (12 to 18☌).The ideal conditions for mushroom pinning are as follows: The Ideal Conditions to Initiate Mushroom Pinning Mushroom Pin Formations Define the Number of Mushroom Yield.How to Provide Ideal Pinning Conditions.The Ideal Conditions to Initiate Mushroom Pinning.Increasing FAE can also help reduce condensation collecting on the casings but try not to let it comprimise the RH. I'd remove the excess moisture on the trays if any,and keep RH around 93% and see how they react for a day or two and adjust accordingly. It looks more like metabolites than contam. You can also take the trays and tilt them to see if water runs out.īe sure to wear a sterile glove to keep your hand on the sub so it don't fall out,and then use the paper towl to soak up any exscess on the surface You can take paper towl and let the paper towl soak up any excess water. Can you suggest any possible ways to save them?" "After an UH malfunction last night they got soaked. (image taken from shroomery for educational purpose) The 2nd pic looks worse than the 1st as far as possible overlay. I rotated and circled spots on your pics to show hyphal knots and what they look like. Not sure if the sparkling effect is water,flash from the camera or hyphal knots,but if they are there before the pic and there is no heavy condensation on the casing then it only leads one to think of hyphal knots. In your pics I see hyphal knots in places. Make sure you hydrogmeter is working correctly.Īnother trick is to use paper towel and very very gently pat the casing One way to help the condensation on your trays is to increase F.A.E,you may also need to readjust you RH. Just try to keep your RH up as much as possible around 93 - 97%(for cased grain) The two behind your temp/ rh gauge also have what appear to be hyphal knots,but those two are looking close to overlay which isn't good.īut I'd like to see closer up of them as well because they look like they may have hyphal knots also.Ĭased grains start fruiting anywhere the 14th - 21st day after cased.ĭunked and rolled cakes can take 3 - 4 weeks to show fruit. I'd like to see them a bit closer up because I thought I saw a couple spots that looked like primordia,a.k.a hyphal knots. From what I can see in the pic,the 3 trays that are more casing than mycelium look fine. ![]()
